I would like to do two things:
First, I want to draw some kind of structure of the web (data) in order to divert discussions about loose term "big data" to specific data topics.
Second, within this structure, I want to highlight the subset which is is considered open data.
Does anyone know if there is anything like that (e.g. a taxonomy tree) already available? Any pointer would be greatly appreciated.
E.g., one example structure of the web (data):
social media a) facebook b) twitter ...
government data
homepages a) individuals b) companies
E-Commerce sites a) Amazon b) EBay ...
Blogs
Weather data
...
Then parts of 2. government data, homepages and weather data could be available as open data...
